    I have the new 5k with an i7, 16GB, 395 card and a 1TB SSD and have been using Lightroom CC and PS since I got the thing. LR has been fairly sluggish (to my dismay), but I remain hopefully that it's an update away from better performance (truly hope).

    I was starting to edit another batch of photos as I usually do this morning and somewhere in the middle of said process the application became insanely slow to respond in every aspect. Everything from editing to scrolling library (small size library currently) to closing the "about Lightroom CC window" takes up to 10 seconds. Zooming isn't even working at all. The cursor keeps freezing and jumping or not displaying at all. My Mail and Browser, etc apps seem normal. Photoshop seems to be running just fine.

    I restarted the app several times (and it closed itself once or twice) and restarted my computer to no avail. Same performance. It's actually entirely useless at this point. I have no idea what happened or how to solve it. I'm running 2015.2.1 release, which I'm fairly certain is the current as I tried the update panel.

    I have 3 unedited projects that I need to get done by tomorrow and it's of some concern. I really don't want to lose or alter my library to any effect. Not sure if uninstalling LR CC and reinstalling would affect library? Not to mention the presets I've loaded and recently purchased/customized.

    Anybody experiencing this? I truly doubt it as it's quite random and I"ve never seen such a lull in performance before in any application.

    Not with that app specifically but what has helped me in similar issues in the past is to uninstall/reinstall the app.

    Unsure if that is an option for you.

    I actually just got off the phone with support--the guy used remote access (always feels a little sketchy IMO), but was surprisingly able to get it back to the performance I was experiencing before. Purged/trashed caches, changed a few other minor settings, restarted the app a few times. Hopefully didn't get into Terminal for anything ha.

    Anyway, while it's still a little sluggish on the new 5k iMac, it's running as it was before. I just hope it doesn't get back to that point and require those actions again. Updates are very much welcome to LRCC!
